This allows the driver of the mobile vehicle to concentrate on driving since spot information is provided in order from the recommended spot where the user has less time to decide whether to stop by, and spot information for multiple recommended spots is not provided at once.
  • the information provision time includes at least the time required to provide the spot information and the time required for the occupant to consider whether or not to visit the recommended spot.
  • the information providing device 100 determines the timing to start providing information so that the provision of spot information about the recommended spot and the consideration of whether or not to visit the recommended spot can be completed before the mobile body reaches the branch point.
  • a unique information provision time is set for each recommended spot.
  • the control unit 180 sets the information provision time to the total time required for voice guidance for each recommended spot and the time required for the occupant to consider whether or not to visit the recommended spot. This allows the occupant of the mobile body to complete the provision of information about the recommended spot and the decision as to whether or not to visit the recommended spot before arriving at the branch point to the recommended spot, and when the occupant decides to visit the recommended spot, the occupant can smoothly head to the recommended spot.
  • the branch point detection unit 150 of the information providing device 100 in this embodiment does not detect a branch point corresponding to the guidance route. This provides only spot information about recommended spots that can be visited without changing the direction of travel on the road currently being traveled, so that when a passenger of the vehicle decides to visit a recommended spot, the passenger can head to the recommended spot smoothly.
  • the control unit 180 of the information providing device 100 determines the timing to start providing information based on the time required to travel from the current position of the mobile object to the branch point and the total information provision time for each recommended spot. In other words, when multiple recommended spots are detected to which the occupant is guided by branching off at the same branch point, the control unit 180 determines the timing to start providing information so that the provision of spot information for the multiple recommended spots and the consideration of whether or not to visit the recommended spots can be completed by the time the mobile object reaches the branch point.
  • the provision of information on the multiple recommended spots and the consideration of whether or not to visit each of the recommended spots can be completed before the vehicle arrives at the branch point to the recommended spots, so that when the vehicle occupant decides to visit a recommended spot, the vehicle occupant can head smoothly to the recommended spot.
  • the control unit 180 of the information providing device 100 in this embodiment provides spot information of the recommended spots that have a short distance from the branch point to the recommended spots. This makes it possible to provide preferentially the spot information of recommended spots that are located at positions that are a short travel distance from the branch point and that are easy for the occupants of the mobile body to stop at.
  • the information providing device 100 may be realized by installing application software that executes the above-mentioned information providing method on a smartphone carried by a user. This makes it possible to provide information about recommended spots to users who are traveling and carrying a smartphone. Furthermore, the information providing device 100 may be realized by incorporating application software for executing the above-described information providing method into the software of a navigation device installed in a mobile object (such as a motorbike or an automobile). This enables the navigation device to provide information on recommended spots and provide route guidance to the recommended spots.
  • a mobile object such as a motorbike or an automobile
  • ⁇ Modification 2> As shown in Figure 10, in a situation in which recommended spot A, for which a guide route is calculated by branching off at branch point P1, and recommended spots B and C, for which guide routes are calculated by branching off at branch point P2, have been detected, if the above-mentioned information provision start time (TBC) is earlier than the predicted time of arrival at branch point P1 (TP1), the information provision time (TA) of recommended spot A is set to a time that is the information provision time (LA) back from the information provision start time (TBC).
  • the control unit 180 starts providing information about recommended spot A from a time that is the information provision time (LA) earlier than the predicted time of arrival at the branch point (TP1), the information provision time (LA) cannot end before the information provision start time (TBC), and as a result, the provision of information about recommended spot B and recommended spot C cannot be completed by the time the moving body arrives at branch point P2.
  • the information provision time (TA) of the recommended spot A is set to a time preceding the information provision start time (TBC) by the information provision time (LA).
  • the processing of the recommended spot extraction unit 130, the guided route calculation unit 140, the branch point detection unit 150, the required time acquisition unit 160 and the control unit 180 of the above-mentioned information providing device 100 is high-speed calculation processing, and therefore the processing may be executed in a server. This allows high-speed calculation processing to be executed in the server, thereby reducing power consumption of the information providing device 100.
  • a mobile terminal such as a smartphone that uses a secondary battery as a power source is operated as the information providing device 100, the power consumption of the mobile terminal can be reduced, thereby extending the continuous operating time of the mobile terminal.
  • REFERENCE SIGNS LIST 100 information providing device 110; communication unit 120; current position acquisition unit 130; recommended spot extraction unit 140; guided route calculation unit 150; branch point detection unit 160; required time acquisition unit 170; providing unit 180; control unit 200; recommended spot server N; network
